Abstract
The 2 (3) Pi-X (3) Pi electronic band system of the aluminum dimer has been measured with the CRLAS technique. While several vibronic bands were examined under high resolution, no rotational features could be d iscerned. Band contours imply a rapid (tau < 10 ps) predissociation in the upper state, explaining why this band system was not observed in previous R2PI and LIF studies. The upper electronic state was determin ed to have a vibrational frequency of 210 +/- 4 cm(-1).
